ELLUMINATED SIGN.

SPECIFICATION forming part of Letters Patent No. 670,188, dated March19, 1901.

Application ledNovemher 1, 1900. Serial No. 35,076. (No model.)

To (AZZ whom, t may concern:

Be it known that I, WILLIAM WEBER, a citizen of the United States ofAmerica, and a resident of Reading, in the county of Berks and State ofPennsylvania, have invented certain new and useful Improvements inIlluminated Signs, of which the following is a specification.

Wy invention relates more particularly to illuminated signal apparatusfor railways, and my main object is to provide for utilizing` thesignal-lanterns commonly employed for the further purpose of clearlyindicating, for instance, the number of the motor carrying the same.

The invention is fully described in connection with the accompanyingdrawings and is specically pointed out in the claim.

Figure l is an elevation, partly in section, of a complete deviceembodying my improvements. Fig. 2 is a plan View of the same. Fig. 3 isa cross-sectional view on the line a; of Figs. 1 and 2.

A represents an ordinary signal-lantern, which is provided, as shown,with bullseye apertures b, c, and clin the wall thereof, of which theaperture b is adapted for special use in connection with my improvedconstruction.

E represents a casing,practically independent of the lantern-case A, butXedly connected to one wall of the latter around a lensaperture b, so asto form a lateral extension projecting considerably beyond thelanterncase, from which the light is thrown into it through saidaperture b. The front wall or face of this casing E is open, as shown,and framed to provide a receptacle f, in which to insert any desiredtransparent slide or slides, as stencil-plate g and glass h, acasing-gate e being provided to permit of their ready insertion andremoval. The closed Walls z' and j of the sign-Casin g are not onlyprovided with reiiecting inner surfaces, but are arranged to converge asthey get farther away from the lantern-case, so that saidreflecting-surfaces .may be nearer to the transparencies g and 72 atpoints farthest from the light. This I nd is of great practicalimportance in order to equalize the illumination, which is naturallygreater near the source of light unless provision be made for equalizingit, as stated.

My improved device is particularly adapted for application tolocomotives instead of the ordinary signal-lanterns which are cornmonlycarried on each side of the smoke-box, thus providing for clearlyshowing at all times the number of the locomotive.

No smoke or dirt can get into the sign-casing to detract from theclearness of the transparencies, which may be readily changed whendesired, and at the same time the whole device is simple, inexpensive,and convenient.

What I claim is- The combination with alantern-case, of an extensionsecured to a lens-apertured Wall thereof consisting of a connectedsign-casing having an open rectangular face framed to receive and holdremovable transparencies, a gated end for introducing and removing thelatter, an inclined top, bottom and rear re- Hector-walls convergingtoward the outer end of the extension to equalize the illumination atvarying distances from the lantern, substantially as set forth. y

Signed at Reading, Pennsylvania, this 27th day of October, 1900.
